How to Look After Dwarf Gourami – A Comprehensive Guide

Dwarf Gourami, also known as Trichogaster lalius, is a popular freshwater fish species in the aquarium trade. These small, brightly colored fish are easy to care for and make great additions to any community tank. However, to keep your Dwarf Gourami healthy and thriving, it’s important to provide them with proper care and maintenance.

Water Conditions

It’s important to keep the water conditions in your Dwarf Gourami tank consistent and within a suitable range. Dwarf Gourami prefer water temperatures between 74-82°F and a pH between 6.0-7.5. It’s also important to maintain a stable water hardness, with a range between 5-15 dGH being ideal.

Tank Size

Dwarf Gourami are small fish, growing to an average of 2 inches in length. As such, they don’t require a large tank, but it’s important to provide them with enough swimming space. A minimum tank size of 20 gallons is recommended for a single Dwarf Gourami, with an additional 10 gallons of space required for each additional fish.


Dwarf Gourami are a freshwater species, so they do not require strong lighting. However, it’s still important to provide them with some light, as it can help to promote plant growth and enhance the overall aesthetic of your tank. A low-intensity LED light will suffice, and you should aim to keep your tank lit for 8-12 hours per day.


Proper filtration is essential for maintaining a healthy Dwarf Gourami tank. A good filtration system will help to remove waste, chemicals, and excess food from the water, keeping it clean and free from harmful toxins. A hang-on-back filter or canister filter is recommended, with a flow rate that provides enough water movement to keep your Dwarf Gourami comfortable.


Dwarf Gourami are omnivores, so they will eat both plant and animal-based foods. A high-quality, balanced diet is essential for maintaining their health, and you should aim to feed them a variety of foods, including pellets, flakes, frozen or live foods, and even some vegetables. Be sure to feed your Dwarf Gourami small, frequent meals throughout the day, rather than one or two large feedings.

Tank Mates

Dwarf Gourami are peaceful, social fish, and they do well in community tanks. However, it’s important to choose tank mates carefully, as some fish can be aggressive or nippy. Good tank mates for Dwarf Gourami include other peaceful species such as tetras, rasboras, and even other species of Gourami.


Dwarf Gourami are relatively easy to breed, and they will often breed in a community tank. To encourage breeding, it’s important to provide them with a suitable environment, including a breeding tank, plenty of plants, and suitable water conditions. The male will build a bubble nest, and when the female is ready to lay eggs, she will lay them in the nest. The male will then fertilize the eggs, and the fry will hatch in approximately 36-48 hours.


Dwarf Gourami are a great choice for any aquarium hobbyist, as they are easy to care for, peaceful, and colorful. With proper care and maintenance, they will thrive in your tank and provide you with years of enjoyment. Just remember to provide them with a suitable environment, a balanced diet, and the
